Donnh, the man who adopted me 10 years ago was an alien of Guara species.
Donnh was tall, muscular and green-skinned, masculine in build, mostly humanoid. Donnh, like all Guaras was a hermaphrodite, having both female and male reproductive organs. Their penis were long and thin, vagina―or maybe cloaca would be a more fitting term for this reproductive porta―tight and inelastic, being just a little slit on their nearly smooth crotch, painfully so for any member of more well endowed species (such as me, a human).
As much as I respected Donnh for being my father figure, I began feeling quite un-filial towards him. With his hermaphroditic pudenda he was the closest thing to a female on this whole raumschiff, and I―an adolescent male―had the urge to breed my adoptive father's tight fertile slit. The thought Donnh might get pregnant by me aroused me only more.
